• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thieu tinh) OR (trieu tinh)) - thanh trung ((cua khong) or (cua phuong)) cang dan thanh lap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu tinh) OR (trieu tinh)) - thanh trung ((cua khong) OR (cua phuong)) cang dan thanh lap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu tinh) OR (trieu tinh)) - thanh trung ((cua khong) or (cua phuong)) cang dan thanh lap".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu tinh) OR (trieu tinh)) - thanh trung ((cua khong) or (cua phuong)) cang dan thanh lap*.
